1 lb. lean ground beef
1 packet of taco or fajita seasoning
1 onion, julienned
1 green or red pepper, julienned
Preheat oven to 350 degrees F and spray an 8x8 inch baking dish lightly with non stick cooking spray. Place ground beef and seasoning into a large mixing bowl, stirring to combine. Transfer beef to prepared baking dish and press down evenly into dish. Bake for about 20 minutes, or until baked through. Remove and drain grease if necessary. While burgers are baking, heat a little olive oil into a large skillet over medium heat. Add sliced onions and bell peppers, stirring until softened. Takes about 5-7 minutes, stirring often.
Split rolls and layer with a burger, onions and peppers, then shredded cheese, and salsa or taco sauce. Serve warm.
